Description

1. Ultra low power transmission with *0mW as the maximal transmitting power 2. ISM frequency band with no require of applying frequency The factory default carrier frequency is **3MHz. (**8/**5MHz available as another type UN) 3. High anti-interference and Low BER (Bit error Rate) Based on the Gaussian Frequency Shift Keying (GFSK) modulation, the high-efficiency forward error correction channel encoding technology is used to enhance data’s resistance to both transient interference and random interference and the actual bit error rate of ***5 ~ ***6 can be achieved when channel bit error rate is ***2 . 4. Long Transmission Distance Within the visible range, when the height of antenna is higher than 2m and The Bit Error Rate (BER) is ***3, the reliable transmission distances respectively is *@********************ud rate is ***0bps, it is more than **0m. When the baud rate is ***0bps, it is more than **0m. 5. Transparent data transmission Transparent data interface used in transceivers is for meeting many standard or nonstandard user protocols. Any false data generated in air can be filtrated automatically (What has been received is exactly what has been transmitted). 6. Multi-channels HAC-UM transceivers offer 8 channels, if needed, *6 or *2 channels available to satisfy various configuration of communication under user ’s demand at the same time 7. 2 ports with three connection methods HAC-UM transceivers provide 2 ports with three connections, ports: a UART interface of TTL level, a non-standard RS***2 port and a non-standard RS***5 port, which both are define by user software (define it just by plugging out and in one short circuit device and then power on). Note: UM**4 (***** ****0bps) is without any non-standard RS***2/**5 port. *****
